FERT. Question-Weed Spraying Included in Bid?

I know this isn't the Pesticide application forum but there is a broader cross section here.

When you bid a fertilizing job do you include spraying for weeds in your bid or is it a separate billing?

I sell 3, 4 and 5 applications of granular fertilizer. Currently I only have 10 accounts but plan on increasing next year. For my 4 and 5 ap programs I include spraying 1 time without billing extra for it. My rates are $5.00 per 1K for the granular. So a 10k lawn gets 5 granular aps and 1 liquid weed application for $250.00 per year. Should I charge for the liquid weed? (same as ap of granular or more or less???)

I am looking to buy a larger sprayer. How do you charge for the liquid weed control and if you want to tell me what product you like best I would appreciate it. I have been using Riverdale Dissolve. Thanks.

i am with both of those guys.
if i pick them up mid season and after say the broad leaf weed control with fert. in may and its september and thet have a lot of clover they are going to be charged little extra.
as for the dissolve: it a three way post-emergent selective herbicide containing amine of 2,4-d,mecoprop and dichlorprop. (info taken out of c-p press book)...
